Abstract: A tipping mechanism for buckets carried by a conveyor or elevator. Each bucket 28 is attached to a chain 26 by a swing link 29 and each bucket carries a sector shape cam 30. As the buckets are carried around a sprocket 27 the cam 30 contacts a peg 31, so as to cause the bucket to progressively tip and empty. The movement of the buckets back to their horizontal position is fully controlled and is smooth by virtue of the contact between a French curve on the cam 30 and a cam surface 35 of substantially wedge shape located above or below the conveyor or elevator chain.

Abstract: Data compression and decompression utilising eg the Ziv-Lempel algorithm is simplified by utilising a tree structure for the dictionary in which alternative symbols at a given position in a symbol sequence (a,b,c) are linked by linking pointers R of a first type and successive symbols (ab,bc,ca,aba,abb,abc) are linked by linking pointers D of a second type. For example the sequence ab may continue with any one of the symbols a,b and c grouped together by R pointers in a list below the final symbol of the sequence ab. Each symbol is defined by an associated pair of D and R pointers, in conjunction with a parent pointer P which identifies its parent. Symbols having no D pointers extending therefrom are pruned from the tree and transferred to a free list as shown in Figure 8(b).

Abstract: A process for production of chlorine dioxide by reacting in a reaction vessel an alkali metal chlorate, a mineral acid and methanol as a reducing agent in propor­tions to generate chlorine dioxide in a reaction medium maintained at a temperature from about 50°C to about 100°C and at an acidity within the interval from about 2 to about 11 N and subjected to a subatmospheric pressure. Thereby water is evaporated and a mixture of chlorine dioxide, water vapour and gaseous by-products is withdrawn from an evaporation region in the reaction vessel. The alkali metal sulphate is precipitated in a crystallization region in the reaction vessel. The content of formic acid in the reaction vessel is increased by addition of formic acid to a content of formic acid exceeding about 0.3 M. The gaseous by-products are condensed to obtain formic acid and the content of formic acid in the reaction vessel is increased by recirculation of the condensate.

Abstract: A tuner station selecting apparatus which has at least two local oscillators like an up, down tuner station selecting apparatus and so on to be used in, for example, a CATV and so on. Accordingly, a tuner station selecting apparatus is capable of effecting a station selecting operation exceptionally better, is simpler in the construc­tion of a tuner metal fitting, and has the same function as before. As the signal for phase-controlling the oscillation frequency of the second local oscillator 7, the second local oscillator frequency signal which leaks into the output of the second intermediate frequency amplifier 5 is obtained. The signal is fed into the external circuit (pre-frequency divider 16, a variable frequency divider 17) so as to reduce the number of the connection terminals. As a result, the external connection portion of the tuner housing member, i.e., the connection location using the through capacitor may be reduced so as to reduce the cost of the parts, thus realizing a tuner station selecting apparatus which is more stable in higher frequency and is simpler in construction.
